Some time ago we decided that we want to replace PHP Explorer with Project Explorer in PHP Perspective [1]. This step should make working with multiple languages more consistent and at some point will simplify PDT code base. I plan to do the switch at the
beginning of next week. From pending issues related to Project Explorer and PDT I know only about problem with Open PHP Type shortcut [2]. I will try fix this during weekend. If someone know about something major enough to prevent this switch let us know.
